A new high performance plan is available for the public, Puffy Pigeon!
The new plan Puffy Pigeon is a dedicated plan. It will give you 4 cores, 15 GB ram, 1000 GB data and you are allowed to set up 500 concurrent connections.
We have also added more data to the other dedicated instances. Happy Hippo will give 100 GB data and Enormous Elephant will give 1000 GB data.
More information about how to get started with ElephantSQL and guides for various languages and platforms can be found here.
